Four-row cylindrical roller bearings are heavy‑duty rolling bearings designed with four rows of cylindrical rollers to provide extremely high radial load capacity and stable performance in demanding applications such as rolling mills, calenders, and roller presses. Their multi‑row construction distributes load evenly across the bearing, allowing reliable operation under high speeds, fluctuating loads, and harsh conditions where durability, reduced friction, and long service life are critical
